| 目的 生产线输送过程中，由于忽略了实际值和模糊论域之间的数值转换，导致分时段生产线输送速度效果差，稳定性低，影响生产线输送设备的运转，为此提出基于PLC技术的生产线输送速度分时段控制模型。方法 根据PLC技术特点，计算生产线输送速度分时段控制量化因子和比例因子，实现输入指令实际值和模糊论域之间的转换;根据工厂对生产线输送速度的实际需求，建立生产线输送速度分时段控制模型，并将量化因子和比例因子计算过程代入，分时段控制生产线输送速度。结果 实验结果表明，对生产线输送速度的控制效果、电机转速波形收敛速度和模型的稳定性进行测试后，与实际控制指令产生的速度阶段变化完全一致，电机转速波形收敛速度最高可达到1100 r/min，幅值裕度维持在10 deg/dB。结论 此次研究的生产线输送速度分时段控制模型，可以根据指令分时段控制生产线输送速度，且在控制生产线的过程中，具有较快的响应速度和较高的稳定性。完成了生产线输送速度分时段控制，为生产线智能化提供参考。 |

| In the transportation process of production line, the numerical conversion between the actual value and the fuzzy universe is ignored, which leads to the poor effect and low stability of the transportation speed of the production line in different periods, and affects the operation of the transportation equipment of the production line. Therefore, a time-sharing control model of the transportation speed of the production line based on PLC technology is proposed. According to the technical characteristics of PLC, the conveying speed of the production line was calculated, and the quantization factor and scale factor were controlled in different periods to realize the conversion between the actual value of the input instruction and the fuzzy universe. According to the actual demand of the factory for the conveying speed of the production line, the control model of the conveying speed of the production line in different periods is established, and the calculation process of the quantitative factor and the scale factor is substituted to control the conveying speed of the production line in different periods. The experimental results show that the control effect of the conveying speed, the convergence speed of the motor speed waveform and the stability of the model are completely consistent with the speed stage changes generated by the actual control instructions. The maximum convergence speed of the motor speed waveform can reach 1100 r/min, and the amplitude margin is maintained at 10 deg/dB. The time control model of the transportation speed of the production line in this study can control the transportation speed of the production line in time according to the instructions, and in the process of controlling the production line, it has faster response speed and higher stability. The conveying speed of the production line is controlled in different periods, which provides a reference for the intelligent production line. |
